Application filed April 10, 1926. Serial No. 101,138.-

My present invention has to do with the reclaiming and sharpening of files; and 1t contemplates the provision of an apparatusfor the purpose indicated that is highly eficient s and expeditious inproducing the results desired on files subjected to its action.

Other objects and practical advantages of the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which Figure 1 is a view, partly in side elevation and partly in longitudinal vertical section,

showing the preferred embodiment of my invention which has been reduced to actual practice and successfully operated.

, Figure 2 is a partial plan and horizontal section of the apparatus. 7 r

1 Figure 3 is a fragmentary view, on anenlarged scale, taken at right angles to Figure 2 and showing a portion of the mechanism, hereinafter explicitly referred to.

" Figure 4 is an enlarged longitudinal section illustrative of one of the peculiar and advantageous nozzles embraced in my improvement. I c i Similar numerals of reference designate corresponding parts in all of the views of the drawings. g I

The main frame 1 of the apparatus may be of the construction illustrated or of any other construction compatible with the purpose of the apparatus, and it is provided at 1 2 with bearings for a crank shaft 3, the said shaft 3being provided with a pulley 4 or other appropriate means for cooperation with a driving connection 5 designed to connect the shaft 3 with an appropriate motor.

The crank of the shaft 3 isdesignatedby 6 and at its end remote from the pulley 4, the shaft 3 is provided withanother pulley 7 for a purpose hereinafter set forth. Said crank 6 is movable in a pendant fixed guard 6" on Carried by and appropriately connected with the 7 frame 1 is a container 10 for grained carborundum, the said container 10 being provided at its upper end with an eduction orifice 11 for air under pressure, steam, or any other fluid under pressure that it is desired to use in the operation of my novel apparatus. tainer 10 is preferably shaped as designated by 12, andin the container 10and arranged adjacent to the eduction orifice 11 are bailies The bottom of the con- 13 and 14, preferably connected alternately to opposite side walls of the container and arranged and constructed as shown in Figure 1. The inner transverse upright wall of the container 10 is provided with a large opening as designated by 15, and in the lower portion of the container 10 is disposed a rotary agitator or stirrer 16, which 6X- tends substantially throughout the width of the container and has for its functionto maintain the carborundum in anragitated state, and to contributetoward the dissemination of the carborundum within the container. The'said stirrer 16 is designed to be driven from the crank shaft 3 through the medium of a belt 17 and apulley 18 on one end of the shaft of the stirrer 16.

Appropriately guided at 20 onthe frame 1 and adapted to be translated longitudinal ly on vthe said frame 1 is atransverse carriage 21 between which and the crank 6 is interposed and connected a pitrnan 22, the said pitman being preferably braced by links 23, interposed betweenand pivotally connected to the carriage 21 and the pitman 22 at an intermediate point in the length of the latter. As illustrated, the said carriage 21 is made up of longitudinal rods 21 movable rectilinearly in guides 21 on the frame verse shaft 26, journaled' in appropriate hearings in the blocks 21 of the carriage 21, and equipped at one end with a crank 27. The racks 24 are formed integral with or are fixedly connected to a transverse bar 28 and form therewith a sub-carriage, and iournaled' and movable endwise in appropriate bearings 31 in said sub-carriage generally des1gnatedby30 1s a transverse shaft 32 equippedwith miter gears 33 and provided atone of its ends with a crank 34. Movable transversely of the apparatus on the forward ends 31 of the bars carrying the rack 24 is abar 29, said bar having slots 32*. receiving said bar ends31", Figure 2.

i Vheels 29 a is arranged and guided in channels 29. in the longitudinal bars of the frame 1, and transverse rods 29 carried by the bar 29 form the axles of and are movable through said wheels 29. It will also be understood that the bar 29 has arms 29 in which the shaft 32 is journaled and that the bar 29 and the shaft 32 are movable together transversely of the apparatus. The bar 29 is equipped with bracket means 40, and journaled in the said bar 29 and bracket means 40 are longitudinally disposed rotary holders 41, appropriately adapted at 42 for the detachable connectionof files, designated by 43. The shaft portions 41 of the holders 41 are provided at their rear ends with miter gears 44, meshed with the miter gears 33 on the shaft 32, and consequently it will be understood, that urning of the crank 34 which is located at one side of the apparatus will be attended by turning of the files 43 about their axes so as to present the said files to the best advantage to the reclaiming and sharpening action of the carborundum in the container 10.

Fulcrumed at an intermediate point of its length to the bar 28 of the sub-carriage 30 is a horizontally-swingable lever 28* connected at 29* to the bar 29; and on the bar 28 is an arcuate'rack 30* for adjustably fixing the lever 28*. Manifestly when lever 28 is sprung out of engagement with said rack, the lever 28 may be swung to move the bar 29 and its appurtenances transversely of the apparatus.

Located in the container 10 below the opening in the front wall thereof is a conduit60 extending transversely of my novel apparatus and adapted to be connected with a source of fluid pressure supply either air or steam. Communicating with the said conduit 60 at intervals in the length thereof and at intervals in the width of the container are nozzles 61, having siphon portions 62 for the suction of carborundum and for the entraining of the carborundum with the air or steam, as the case may be, jetted at 63 in the nozzles and in alinement with the eduction orifices 64 thereof.

- In the practical operation of my novel apparatus, it will be noted from the foregoing that when the shaft 3 is driven, the carriage 21 will be reciprocated on the frame 1 for the advancement of the files through the said opening 15 in the front wall of the carborundum container and for the alternate retraction of the files, and that while the files are in the carborundum container they will be subjected to the blasts of carborundum from the nozzles 61 with the result that the filesdwill be reclaimed and adequately sharpene Incident to the operation the files are turned about their axes through the me- .dium of the crank 34; and it will also be understood that the adjustment of the subcarriage 30 on thercarriage 21 permits of the files being projected into the carborundum container 10 to. a greater or less extent as is deemed expedient, and that the transverse adjustment of the bar 29 and the parts carried thereby, relative to the sub-carriage 30, is also materially advantageous in the sharpening of the files, and also to take care of various length files.

It will be apparent from the foregoing that notwithstanding the capacity of function of my apparatus, the apparatus is not unduly complicated, and, as a whole. is well adapted to withstand the usage to which apparatus of corresponding character is ordinarily subjected.

I have entered into a detailed description of the construction and relative arrangement of the parts comprised in the present and preferred embodiment of my invention in order to impart a full, clear and exact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the specific construction and relative arrangement of parts as disclosed, my invention being defined by my appended claims within the scope of which changes in structure and changes in arrangement may be made without departure from my invention.
